Abstract: A method for operating a driver assistance system of a vehicle includes the steps of: checking whether there is a motorway exit or roadworks on a first side of the vehicle; checking whether an environment sensor system of the vehicle detects a lane marking that bounds a lane of the vehicle on a second side, which is opposite the first side; if the result of the checking is that there is a motorway exit or roadworks on the first side of the vehicle and that the environment sensor system detects the lane marking, operating a lane-keeping function of the driver assistance system; and if the result of the checking is that there is a motorway exit or roadworks on the first side of the vehicle and that the environment sensor system does not detect the lane marking, triggering a takeover request to a driver of the vehicle.

Abstract: The present disclosure relates to a driving assistance system for a vehicle, which is designed to detect one or more factors providing one or more items of guidance for a situation in which the vehicle finds itself, to detect a confirmation action performed by a vehicle occupant; and to execute a driving assistance function according to the detected factor or the detected factors and according to the detected confirmation action. An influence of the detected confirmation action on the executing of the driving assistance function is weighted according to a reliability value associated with the vehicle occupant, which has been determined by the driving assistance system on the basis of confirmation actions performed by the vehicle occupants in different situations in the past.

Abstract: A method for securing a geographic position of a vehicle includes scanning multiple information sources, which each provide items of information which indicate the position of the vehicle; determining individual positions on the basis of each of items of information of one of the information sources and items of surroundings information in the region of a position hypothesis; validating items of information, the associated individual position of which deviates by not more than a predetermined amount from the position hypothesis; determining the position of the vehicle on the basis of the validated items of information, wherein a change of a quality of the items of surroundings information is determined; and, on the basis of the change, determining a probability at which the determined position deviates by more than the predetermined amount from an actual position.
